MARKER.

Specification of Letters Patent.

Patented April 30, 1907.

Application filed June 27,1906. Serial No. 323,599.

To all whom it may concern.-

Be it known that I, CARL Brzexnnxx, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Marker, of which the following is a full, clear, and exact description.

This invention relates to a marker or marking device adapted to be used by tailors or artisans for marking or laying out work.

T ie object of the invention is to produce a device of this kind which is simple in construction and which may be operated readily to produce a clear and well defined mark.

The invention consists in the construction and combination of parts to be more fully described hereinafter, and particularly set forth in the claims.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the ligurcs.

Figure 1 is a side elevation of the preferred form of the device; Fig. 2 is an edge view of the device shown in Fig. 1 at the point where the marker is mounted; Fig. 3 is a cross section through the device shown in Figs. 1 and taken upon the line 3-3 of Fig. 2; Fig. 1

is a perspective showing a modified and simpler form of the device; and Fig. 5 is a side elevation showing another modified form, certain parts being broken away and shown in section.

Referring more particularly to the parts and especially to Figs. 1 to 3, 1 represents a case which has substantially the form of a watch case, presenting two sections or covers 2 which are connected together by a spring hinge 3. At a point opposite the spring hinge 3 the edges of the cover are cut away so as to form an opening 4. In this opening there is mounted a marker 5 having the form of a wheel as indicated, said wheel having a thin marking edge 6. This wheel is rota tably mounted upon a pin 7 and is disposed substantially in the central axial plane of the case 1, but in a slightly inclined position, as shown. WVithin the interior of the case 1 the covers 2 are provided with a transverse guide bar or guide plate 8 which is provided near its middle point with a longitudinally extend ing slot 9. This guide plate is disposed quite near the side wall of the case, and is provided on the side adjacent to this wall with a spring 10. The said spring may have substantially the form shown in Fig. 3, being attached at 11 to the plate and having two coils 12 and an extension 13 which .is preferably curved and projects across the face of the guide plate as indicated. \Vithin the case and between the side wall thereof and the guide plate 8, I provide a small wheel 14, the periphery whereof is provided with a groove 15, and this groove receives the curved extension 13 so that the spring operates to press the wheel toward the marking wheel 5. The face of this wheel 1 1; is pressed against the side of the guide plate 8, and it is formed with an upwardly projecting stud 16 which projects through the slot 9 as indicated. Upon this stud 16 there is rotatably mounted a cartridge 17 which is composed of any suitable marking substance such as chalk or soapstone. When the cartridge is placed upon the stud 16, the resiliency of the spring 10 operates to hold the edge thereof against the edge of the marker or wheel 5. When the marking device is to be used, the wheel 5 is applied to the surface to be marked, and is advanced in the plane in which it rotates. The inner edge of this marking wheel, in passing across the edge of the cartridge, wipes off a quantity of the marking substance, which becomes transferred upon the surface to be marked. With this arrangement, the wheel 5 will quickly wear a circumferential groove 18 in the edge of the cartridge, it being understood that as the wheel 5 rotates, it will operate to rotate the cartridge upon the stud 16. In this connection, special attention is called to the in clined position of the planes of rotation of the cartridge and marker with respect to each other. This arrangement, while it e11- ables the marker to rotate the cartridge, it also brings about a rubbing or wiping movement which materially assists the transfer of the marking substance from the cartridge to the wheel. \Vhcn the cartridge becomes substantially consumed, a new cartridge may be readily placed in the case, as will be readily understood.

In Fig. 4 I illustrate a modified form, which is of very simple construction. In this form, the cartridge 19 is not supported within a case, but is simply held against the face of a guide finger 20 which projects up from a tang 21, said -tang being secured in the handle 22.

At the junction between the guide finger 20 and the tang 21, a marker or wheel 23 is pivotally mounted, the same being disposed in a plane which is inclined with respect to the. plane of rotation of the cartridge in the manner suggested above. The cartridge 19 is! provided with an opening receiving a trans-. versely projecting pin 24, to which pin is attached the extremity of a coiled spring 25, the inner extremity of which spring is attached to the finger at a suitable point as shown. From this arrangement, the spring evidently operates to maintain the edge of the cartridge in contact with the marker 23. While this form of the device embodies the general principle of the invention, it is very simple and easily constructed.

In Fig. 5 I illustrate a second modified form in which the case 26 is cylindrical, having an opening 27 formed near one extremity thereof. In the outer side of the case adj acent to this opening, a bracket 28 is attached, which carries an inclined marker wheel 29, and the edge of this wheel projects into the interior of the case through the opening 27, as shown. The cartridge 30 is given the form of a stick or candle, and the arrangement is such that its inner extremity is adapted to be engaged by the edge of the wheel 29. The cartridge is formed with a central bore 31 which receives a guide stem 32, and this guide stem extends beyond the butt end of the cartridge as shown, and is rotatably mounted in a removable cap 33 mounted on the rear end of the case as shown. Toward the butt of the cartridge the stem 32 is provided with threads 34 upon which is mounted an adjusting nut 35. Against this nut a coiled spring 36 thrusts, the inner extremity of said spring thrusting against a washer 37 which is slidably mounted on the stem and abuts against the butt end of the cartridge as shown. It should be understood that the pressure of the spring maintains the end of the cartridge against the marking wheel. With this form of the device, it should be understood that the same wiping effect of the marking edge across the face of the cartridge, is provided, resulting in forming a depression or cup 38 in the end of the cartridge. The forward end of the stem 32 is received in a socket 32 formed in the forward head of the 1 case as shown. The nut is provided with laterally projecting fingers 39 which project through guide slots 40 formed in the side wall of the case, and these prevent the nut from rotating when the spring 36 is to be adjusted. In this connection, it should be understood that by rotating the stem 32 in the cap or head 33, the nut 35 may be made to advance upon the threads 34.

claim as new and desire to secure by Letters Patent:

1. In a device of the class described, in combination, a member carrying a rotatable marker, means for supporting a cartridge rotatably on said member, and means for pressing said cartridge against the face of said marker said marker affording means for rotating said cartridge, said marker being disposed ina plane inclined with respect to the axis of said cartridge whereby the edge of said marker wipes laterally on said cartridge.

2. In a device of the class described, in combination, a member carrying a marking wheel rotatably mounted thereupon, means for rotatably mounting a cartridge on said member, means for guiding said cartridge to move in the direction of said wheel, and means for pressing said cartridge against the edge of said wheel, said wheel being disposed in an inclined position with respect to the plane of rotation of said cartridge.

3. In a device of the class described, in combination, a case presenting a guide pin, a cartridge having a bore received over said guide pin, a rotatable marker mounted in said case, and a spring adapted to press said cartridge against the face of said marker whereby the rotation of said marker will ro tate said cartridge, said marker being disposed in an inclined plane with respect to the plane of rotation of said cartridge.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
